The Gain Paradox

Progress in Biophysics and Molecular Biology, 2009
Chemoreceptors in Escherichia coli control the activity of a kinase that phosphorylates a response regulator that, in turn, biases the direction of rotation of flagellar motors, affecting the manner in which cells swim. A small change in receptor occupancy induces a large change in kinase activity.

Correlation between genetic polymorphisms and stroke recovery: analysis of the GAIN Americas and GAIN International Studies. [PDF]

, 2012
Background and purposeRecovery after stroke occurs on the basis of specific molecular events. Genetic polymorphisms associated with impaired neural repair or plasticity might reduce recovery from stroke and might also account for some of the intersubject

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Multiuser Diversity Gain in Cognitive Networks [PDF]

, 2010
Dynamic allocation of resources to the \emph{best} link in large multiuser networks offers considerable improvement in spectral efficiency. This gain, often referred to as \emph{multiuser diversity gain}, can be cast as double-logarithmic growth of the ...

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.
